Climate Change is something that isn’t being given as much attention to in the United States. Our group’s intention is to analyse the change in average temperature here, along with the change in CO2 emissions and try to find a correlation.

We will be using two data sets in our project, one for the average temperature seen in the US per year, along with CO2 emissions seen per country. We plan on filterng our the CO2 emissions for just data seen in the US for most of our analysis.

Our CO2_emissions file has information on the sources from which these CO2 emissions come from (ie residential buildings, manufacturing sites), so we will use our information_df.csv file to help us read the information in our CO2_emissions.csv. Our source for this information is the same source we used for CO2_emissions.csv, as hyperlinked in the above paragraph.

Conclusions on Yearly Temperatures

More specifically, the highest mean temperature seen from 1991 is 9.0308367. We expected that this would be seen in 2016 as our data consistently shows us that this has been the hottest year. The lowest mean temperature was 6.7306267, occuring in 1996. From this data too, we can conclude that temperature has been rising over the last 26 with a total rise in average of 7.6169996. This helps answer the first part of our second question – 2016 was the hottest year.

CO2 Emissions and Temperature

Year Total CO2 Emissions Change in Temperature
2004 7244272 7.713543
2005 7182808 7.931033
2007 7128952 7.879380
2006 6994087 7.971669
2003 6991255 7.729782
2002 6981787 7.794915
2000 6969124 7.496298
2001 6821236 7.633218

1998 6749016 8.097573
2010 6713349 7.591250
2008 6648991 6.990188
2009 6604069 7.167375
2011 6571654 7.548140
2012 6343841 8.173909

Our table above displays the yearly temperatures along with the CO2 emissions seen and the temperature in that year. This would help us in understanding and answering our question of if there is a correlation seen between emissions and temperature. Our table is sorted by total CO2 emissions, for ease in looking at the years with the worst CO2 emissions. Our data consists of the years 1998-2012. 2012, the most recent year, has the highest change in temperature with the least amount of total emissions. 2009, the year with the second least change in temperature is also the year with the 3rd least total emissions of CO2. This helps us in answering our first question – if there is a correlation between rise in average temperature and CO2 emissions. The linear regression is 0.1984574, so there doesn’t seem like there’s much of a correlation between the temperature change and total CO2 emissions seen per year, as the data from the table suggests. To answer the second question, our hottest year is not the year with the most CO2 emissions.

Comparison of Personal Expenditures & CO2 emissions

Comparing the total consumption of fuel from personal expenditure in 2000 and 2015, we can see that most consumption has varied by about 2%, except for residential, commercial and public services. The greatest increase in fuel consumption in these 2 years is transport, which could vary over a multitude of reasons such as an increase in air travel and a decrease in use of public transport in America. The intention of using a pie chart was to compare different years and easily look at categories that consume more fuel than others. In this case, electricity and heat consistently are the highest categories in fuel consumption, almost occupying half of the pie chart. This helps us in answering our third question, being where does most fuel consumption come from.

CO2 Emissions (kt) around the World

Our group was curious to see how each country differed from each other with their changes in CO2 emissions over 17 years. This chart was intended to see if other countries outperform others in terms of their CO2 emissions, or if all countries produced around the same amounts of CO2. As we can see extremely clearly, China has had the highest amount of change in CO2 emissions (6.96M), with India having the second highest(1.30M). We can also observe that Middle Eastern & Asian countries tend to have a greater change in these emissions compared to other countries. These changes in CO2 emissions (in India & China particularly) would probably also explain them being countries with a notable amount of air pollution.. From this, we can also see that an outlier is the United States (because of how light its color is in comparison with other countries) with -146.73k of change.
